BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a childproof perfume bottle.

2. Description of the Related Art

Conventional perfume bottles are not childproof. Since the alcoholcontent of perfumes is usually high, opening the same by a child hashidden dangers.

SUMMARY OF THE INVENTION

In view of the above-described problems, it is one objective of theinvention to provide a perfume bottle that is difficult for children toopen.

The childproof perfume bottle has a simple structure, safe design, andlow production costs.

To achieve the above objective, in accordance with one embodiment of theinvention, there is provided a perfume bottle comprising a bottle bodyand a bottle cap covering the bottle body. The bottle body comprises anupper connection part comprising an external wall comprising a malescrew. The bottle cap comprises an internal wall comprising a femalescrew matching the male screw of the external wall. The external wall ofthe upper connection part comprises a bulge, and a stop piece isdisposed at one end of the bulge. The internal wall of the bottle capcomprises a clamping block which is capable of tightly fitting the bulgeof the external wall after revolving the bottle cap to a certain angle.

In a class of this embodiment, a transition slope is disposed at anotherend of the bulge to facilitate the clamping block to slide to fittightly the bulge.

In a class of this embodiment, a clamping slope is disposed at one endof the clamping block to facilitate the clamping block to slide to fittightly the bulge.

In a class of this embodiment, the male screw of the external wall ofthe bottle body comprises a starting point at a lower part of theexternal wall and an end point at an upper part of the external wall,and the bulge and the stop piece are disposed at front of the startingpoint of the male screw.

In a class of this embodiment, the female screw of the internal wall ofthe bottle cap comprises a starting point at a lower part of theinternal wall and an end point at an upper part of the internal wall,and the clamping block is disposed at front of the starting point of thefemale screw.

In a class of this embodiment, the stop piece, the bulge, and thetransition slope are integrated, and the bottle body, the stop piece,the bulge, and the transition slope are integrated.

In a class of this embodiment, the clamping block and the clamping slopeare integrated, and the bottle cap, the clamping block, and the clampingslope are integrated.

In a class of this embodiment, an air vent is disposed at a top surfaceof the bottle cap.

In a class of this embodiment, a sealing ring is disposed at a lowerpart of the external wall of the upper connection part of the bottlebody, and the stop piece, the bulge, and the transition slope aredisposed above the sealing ring.

In a class of this embodiment, upper surfaces of the clamping block andthe clamping slope are a convex arc in shape.

Advantages according to embodiments of the invention are summarizedbelow. The bottle body of the perfume bottle and the bottle cap of theperfume bottle are in nonrigid connection. When the bottle cap isscrewed up, the clamping block of the internal wall of the bottle captightly fits the bulge of the external wall of the bottle body. Theclamping between the clamping block and the bulge is so tight that achild has no enough strength to detach the clamping block from thebulge. Thus, the child cannot remove the bottle cap from the bottlebody. Only an adult who has enough strength can do so. Therefore, theperfume bottle of the invention is safe for children, which has a simplestructure, safe design, and low production costs.

DETAILED DESCRIPTION OF THE EMBODIMENTS

For further illustrating the invention, experiments detailing achildproof perfume bottle are described below. It should be noted thatthe following examples are intended to describe and not to limit theinvention.

A perfume bottle comprises a bottle body 1 and a bottle cap 2 coveringthe bottle body 1. The bottle body 1 comprises an upper connection part11 comprising an external wall 12 comprising a male screw 13. The bottlecap 2 comprises an internal wall 21 comprising a female screw 23matching the male screw 13 of the external wall 12. The external wall 12of the upper connection part comprises a bulge, and a stop piece 15 isdisposed at one end of the bulge 14. The internal wall 21 of the bottlecap 2 comprises a clamping block 24 which is capable of tightly fittingthe bulge 14 of the external wall 12 after revolving the bottle cap to acertain angle. When the bottle cap 2 is screwed up and is connected tothe upper connection part 11 of the bottle body 1, the clamping block 24of the internal wall of the bottle cap 2 tightly fits the bulge 14 ofthe external wall of the bottle body. The clamping between the clampingblock 24 and the bulge 14 is so tight that a child has no enoughstrength to detach the clamping block 24 from the bulge 14. Thus, thechild cannot remove the bottle cap 2 from the bottle body 1. Only anadult who has enough strength can do so.

A transition slope is 16 disposed at another end of the bulge 14 tofacilitate the clamping block 24 to slide to fit tightly the bulge 14. Aclamping slope is 25 disposed at one end of the clamping block 24 tofacilitate the clamping block 24 to slide to fit tightly the bulge 14.

The male screw 13 of the external wall 12 of the bottle body comprises astarting point 131 at a lower part of the external wall 12 and an endpoint 132 at an upper part of the external wall 12, and the bulge 14 andthe stop piece 15 are disposed at front of the starting point 131 of themale screw. The female screw 23 of the internal wall 21 of the bottlecap comprises a starting point 231 at a lower part of the internal wall21 and an end point 232 at an upper part of the internal wall 21, andthe clamping block 24 is disposed at front of the starting point 231 ofthe female screw.

The male screw 13 of the external wall 12 of the bottle body and thefemale screw 23 of the internal wall 21 of the bottle cap arecontinuously convex or concave. Thus, the moving of the bottle cap onthe bottle body is unidirectional.

The bottle body 1 and the bottle cap 2 are cylindrical, conical, orelliptic cylindrical. The bottle body 1 and the bottle cap 2 can be madeof plastic, metal, glass and other materials by one-step injectionmolding.

The stop piece 15, the bulge 14, and the transition slope 16 areintegrated, and the bottle body 1, the stop piece 15, the bulge 14, andthe transition slope 16 are integrated by injection molding with plasticas raw materials.

The clamping block 24 and the clamping slope 25 are integrated, and thebottle cap 2, the clamping block 24, and the clamping slope 25 areintegrated by injection molding with plastic as raw materials.

The diameter of the upper connection part 11 of the bottle body 1 isless than the diameter of the bottle body 1. The diameter of the upperconnection part 11 of the bottle body 1 is slightly smaller than thediameter of the bottle cap 2 so that the bottle cap can cover the upperconnection part 11 of the bottle body. The height of the upperconnection part 11 of the bottle body is slightly smaller than that ofthe bottle cap.

An air vent 20 is disposed at a top surface of the bottle cap 2. The airvent 20 can be any through hole having any shapes. The number of the airvent 20 is one or more.

A sealing ring 17 is disposed at a lower part of the external wall 12 ofthe upper connection part of the bottle body, and the stop piece 15, thebulge 14, and the transition slope 16 are disposed above the sealingring 17.

The stop piece 15, the bulge 14, and the transition slope 16 are tightlyattached to the external wall 12 of the bottle body. The stop piece 15is higher than the bulge 14. When the clamping block 24 slides along thetransition slope 16 to lean against the stop piece 15, the front end ofthe clamping block 24 is impeded by the stop piece, whereby fixing thebottle cap 2.

The clamping block 24 is a curved strip protrusion tightly attached tothe internal wall of the bottle cap. Optionally, the clamping block 24is a convex block, a convex point, or a convex ring. The upper surfacesof the clamping block 24 and the clamping slope 25 are a convex arc inshape.

While particular embodiments of the invention have been shown anddescribed, it will be obvious to those skilled in the art that changesand modifications may be made without departing from the invention inits broader aspects, and therefore, the aim in the appended claims is tocover all such changes and modifications as fall within the true spiritand scope of the invention.
